3D VLSI: A Scalable Integration Beyond 2D

TLDR
3D VLSI (3DV) is an emerging 3D integration technology that unlike packaging-driven 3D technologies can deliver orders of magnitude more integration densities due to extremely small sizes of vertical vias.
Abstract
As the semiconductor industry faces serious challenges extending the CMOS roadmap, traditional cost reduction benefits that accompanied power/performance/area (PPA) advantages of successive technology nodes have decreased due to a myriad of process integration challenges and increased variability, reliability, power and thermal constraints. 3D integration technologies have been pursued as a potential solution to help integrate more functions within a confined available dimensions of advanced mobile devices. 3D VLSI (3DV) is an emerging 3D integration technology that unlike packaging-driven 3D technologies (e.g., 2.5D, TSV-based 3D, etc.) can deliver orders of magnitude more integration densities due to extremely small sizes of vertical vias. In this paper, we describe the 3DV technology and its current benefits and challenges. We also survey recent literature that show the potential of 3DV to help continue Moore's law trajectory beyond 2D.

Impact of Electrostatic Coupling and Wafer-Bonding Defects on Delay Testing of Monolithic 3D Integrated Circuits

TL;DR: The results show that the timing characteristics of an M3D IC can be significantly altered due to coupling and wafer-bonding defects if the thickness of its ILD is less than 100nm, and test-generation methods must be enhanced to take M3d fabrication defects into account.

Analysis of electrostatic coupling in monolithic 3D integrated circuits and its impact on delay testing

TL;DR: The results show that significant rethinking in test generation is needed to effectively screen delay defects in M3D ICs and the impact of coupling on the effectiveness of delay-test patterns using the statistical delay quality level (SDQL) as a metric.
